摘要:
The invention relates to a multicolor electrophoretic ink comprising at least four types of particles that are dispersed in a non-polar organic medium. Each type of particles contains a pigment of a color associated therewith and has a positive or negative electrostatic charge. The invention is characterized in that at least one of said types of particles has a magnetic property (magnetic core) such that each type of particles can migrate in a predefined manner under the combined effect of an electrostatic force and/or a magnetic restoring force.

The invention relates to novel block copolymers that enable a good dispersion of nanofillers in water and also to a dispersion of nanofillers obtained owing to these block copolymers. This dispersion may be used as a transparent electrode in organic solar cells or other photoemitter or photoreceptor devices.
